Why can't I take a shower on my first day in Lhasa?

When taking a bath, because the temperature of hot water rises, it is easy to have a sense of hypoxia. In addition, a large amount of water vapor reduces the oxygen content in the bathroom, which is a relatively narrow and closed space. In this case, it is easy to lack oxygen, but it is a very dangerous thing in Tibet.

In Tibet, the temperature difference in one day is quite large, and it is very cold in the morning and evening, usually only 0 degrees. If you take a bath at night, it is easy to cause a cold, or altitude sickness caused by excessive physical exertion in bathing. After a few days in Tibet, there will be no problem. Moreover, it should be noted that Tibet's climate is dry, so you can't take a bath with too hot water or take a bath for too long.
